Is there a torch you'd recommend for heating a crucible?
Something to add to the gold so it won't stick, or ?
All ideas welcomed, thanks in advance!

A little boric acid along with the gold to be melted in the little crucible will do. Just put a pinch (I don't know how many or how big a piece are you trying to melt?). Point the torch at it on low setting so it wouldn't blow away all of the boric acid. The Boric acid will melt and look like molten glass (this will take 10-15 seconds). Now its time to give it more propane or whatever gas you will be using. The melted gold will separate itself and the ceramic crucible. You can pour the melted gold over a metal plate and let cool. Make sure you oil it first so it wouldn't stick. 3 in 1 oil will do the trick. dip it in some water to cool it.
